Nasa has captured video of the largest explosion ever seen on the Moon's surface.
A meteor smashed into the Moon back in March, causing a bright burst of light visible with the naked eye.
The impact of the 40kg rock was not seen in real time, but was noticed later by an analyst reviewing footage taken by satellites pointed at the Lunar surface.

It is thought the meteor was part of a larger shower of rocks originating from the asteroid belt, which also reach Earth before disintegrating in our atmosphere.
"We'll be keeping an eye out for signs of a repeat performance next year when the Earth-Moon system passes through the same region of space," said Bill Cooke at Nasa's Meteoroid Envirvonment Office.
The space agency is watching to learn more about periodic space weather, and its potential impact on future missions to the Moon.
